Legal Proceedings On April 1, 1999, the Company reported a release of approximately 7,800 lbs. of R-11 refrigerant (the “1999 Release”), at its former leased facility in Hillburn, NY (the “Hillburn Facility”), which the Company vacated in June 2006. A failed hose connection to one of the Company's outdoor storage tanks allowed liquid R-11 refrigerant (“R-11”) to discharge from the tank into the concrete secondary containment area in which the subject tank was located. Between April 1999 and May 1999, with the approval of the New York State Department of Environmental Conservation (“DEC”), the Company constructed and put into operation a remediation system to remove R-11 levels in the groundwater under and around the Hillburn Facility. In September 2000, the Company signed an Order on Consent with the DEC, which was amended in May 2001, whereby the Company agreed to operate the remediation system and perform monthly testing at the Hillburn Facility until remaining groundwater contamination has been effectively abated. In July 2005, the DEC approved a modification of the Order on Consent to reduce the frequency of testing from monthly to quarterly. The Company is continuing to operate the remediation system pursuant to the approved modifications to that Order on Consent. In December 2012, the Company met with representatives of the DEC and has proposed further modifications to the Order of Consent to further reduce the frequency and scope of testing, and expects to finalize these modifications during the first half of 2013. Based upon the Company’s recent discussions with the DEC, as of December 31, 2012, the Company accrued, as an expense in its consolidated financial statements, the costs that the Company believes it will incur in connection with its compliance with the Order of Consent through December 31, 2017. There can be no assurance that additional testing will not be required or that the Company will not incur additional costs and such costs in excess of the Company’s estimate may have a material adverse effect on the Company financial condition or results of operations. In May 2000, the Hillburn Facility, as a result of the 1999 Release, was nominated by the United States Environmental Protection Agency (“EPA”) for listing on the National Priorities List (“NPL”) pursuant to the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (“CERCLA”). The Company submitted opposition to the listing within the sixty-day comment period. In September 2003, the EPA advised the Company that it has no current plans to finalize the process for listing of the Hillburn Facility on the NPL and that the EPA will not withdraw the proposal for listing on the NPL. The Company has exhausted all insurance proceeds available for the 1999 Release under all applicable policies. During the years ended December 31, 2012 and 2011, the Company incurred $102,000 and $86,000, respectively, in additional remediation costs in connection with the matters above. There can be no assurance that the ultimate outcome of the 1999 Release will not have a material adverse effect on the Company's financial condition and results of operations. There can be no assurance that the EPA will not change its current plans and seek to finalize the process of listing the Hillburn Facility on the NPL, or that the ultimate outcome of such a listing will not have a material adverse effect on the Company's financial condition and results of operations. Employment Agreement The Company has entered into a two-year employment agreement with Kevin J. Zugibe, which currently expires in October 2014 and is automatically renewable for successive two-year terms unless either party gives notice of termination at least ninety days prior to the then expiration date of the then current term. Pursuant to the agreement, Mr. Zugibe is receiving an annual base salary of $288,500 with such increases and bonuses as the Company’s Board of Directors may determine. The Company is the beneficiary of a "key-man" insurance policy on the life of Mr. Zugibe in the amount of $1,000,000.
